Asymptotic limits of the attached eddy model derived from an adiabatic atmosphere
Yue Qin, Gabriel G. Katul, Heping Liu +1
The attached-eddy model (AEM) predicts mean velocity and streamwise velocity variance profiles that follow a logarithmic shape in the overlap region of high Reynolds number wall-bo…
The vertical velocity skewness in the atmospheric boundary layer without buoyancy and Coriolis effects
Elia Buono, Gabriel Katul, Michael Heisel +4
One of the main statistical features of near-neutral atmospheric boundary layer (ABL) turbulence is the positive vertical velocity skewness above the roughness sublayer or t…
The vertical-velocity skewness in the inertial sublayer of turbulent wall flows
Elia Buono, Gabriel Katul, Michael Heisel +4
We provide empirical evidence that within the inertial sub layer of adiabatic turbulent flows over smooth walls, the skewness of the vertical velocity component displays uni…
Revisiting a drag partition model for canopy-like roughness elements
Elia Buono, Gabriel G. Katul, Davide Vettori +2
Turbulent flows over a large surface area (S) covered by n obstacles experience an overall drag due to the presence of the ground and the protruding obstacles into the flow. The dr…
The advancing wave front on a sloping channel covered by a rod canopy following an instantaneous dam break
Elia Buono, Gabriel G. Katul, Davide Poggi
The drag coefficient for a rigid and uniformly distributed rod canopy covering a sloping channel following the instantaneous collapse of a dam was examined using flume experi…
Estimating scalar turbulent fluxes with slow response sensors in the stable atmospheric boundary layer
Mohammad Allouche, Vladislav I. Sevostianov, Einara Zahn +5
Conventional and recently developed approaches for estimating turbulent scalar fluxes under stable conditions are evaluated. The focus is on methods that do not require fast scalar…
